When their village is reduced to ash, Nox and Juro are thrust into a world they never knew existed — a world ruled by Iora, the life force that fuels monsters, demons, and warriors alike. Stripped of everything they’ve ever known, the two must survive in a brutal land where every shadow hides a predator, and every ally has their own secrets. But survival is just the beginning. As they train and fight to master their Iora, they uncover unsettling truths — about the demons that feast on human suffering, about the ones who created them, and about the strange power sleeping inside Nox himself. The deeper they go, the more the line between prey and predator begins to blur. And somewhere beyond the darkness, something ancient stirs — watching, waiting, hungering.
